Yes you can do that. But after transcode the file has a "real" .nuv
"header"/envelope, so you need the dsmyth filter
(dsmyth.sf.net<http://dsmyth.sf.net>)
to be able of using the .nuv file on Windows. In addition you need a MPEG4
codec on your Windows PC.

When you have transcoded the file to MPEG4, you can replace the header with
the nuv2avi application (on Linux!), which without recoding creates an MPEG4
AVI file from the nuv file. Note that time stamps in the nuv file are lost,
so you might get audio sync problems with the resulting AVI file, especially
if you have the recording from a noisy source.
The dsmyth filter and nuvexport to DIVX format are methods that handle the
time stamps correctly in my experience.

Also note that the dsmyth filter is a "Direct Show" filter and not a "Video
for Windows" filter. So with dsmyth you can use nuv files in "Direct Show"
players such as Windows Media Player and ZoomPlayer, but you can not use it
in Windows video editing applications, that require "Video for Windows"
access to the video file.
